Abstract

A steering column is provided to destroy a steering column by a collapse cylinder, to secure the distance between a steering wheel and a human body, and to minimize the shock applied to a human body. A cylindrical steering column(1) for connecting a steering wheel(3) having an air bag(2) built-in and a steering shaft(4) for transmitting steering force to the steering device of a steering apparatus to each other is provided. A destruction cylinder(7) having an explosive exploded by the control of an ACU built-in is provided on one side of the steering column. The steering column of the steering apparatus is controlled by the ACU when the vehicle collides with an object so that the air-bag is emitted and that the explosive is exploded to destroy the destruction cylinder. Therefore, the length of the steering column is reduced and the steering wheel moves to the steering shaft to increase the distance between the steering wheel and the human body and to increase the shock absorption space of the air-bag. Therefore, the shock applied to the human body is significantly absorbed by the air-bag to be offset so that the damage of the body caused by the shock is reduced.

본 발명은 차량의 조향장치의 조향컬럼에 관한 것으로서, 보다 상세하게는 차량의 정면 충돌시에 에어백의 충격흡수 공간을 확보할 수 있도록 전면 충돌시 ACU의 제어에 의해 폭발하여 그 길이를 축소시킴으로써 조향휠이 전방으로 이동가 능하게하여 에어백의 충격흡수공간을 증대하여 승객에게 가해지는 충격력을 현저히 감쇄할 수 있도록 된 차량의 조향장치의 조향컬럼에 관한 것이다.The present invention relates to a steering column of a steering apparatus of a vehicle, and more particularly, to steer by exploding and reducing the length of the steering by the control of the ACU during frontal collision so as to secure the shock absorbing space of the airbag during the frontal collision of the vehicle. The present invention relates to a steering column of a steering device of a vehicle, which enables the wheel to move forward to increase the shock absorbing space of the airbag, thereby significantly reducing the impact force applied to the passenger.

일반적으로 차량의 조향장치는 자동차의 진행 방향을 임의로 바꾸기 위한 장치로 운전자가 직접 조향조작을 하여 그 조작력을 기어기구 및 링크기구로 전달하는 조작기구가 포함되어 잇다.In general, a steering device of a vehicle is a device for arbitrarily changing the driving direction of a vehicle, and includes a steering mechanism for directing steering by a driver and transmitting the operating force to a gear mechanism and a link mechanism.

상기한 조작기구는 도 3 및 도 4에서 도시된 바와 같이 차량(51)의 전반부에 마련되며 조향휠(52), 조향축(53) 및 조향컬럼(54)으로 이루어지며 상기에서 조향컬럼(54)은 상기 조향축(53)을 감싸는 일종의 튜브로써 차량의 전방충돌시에 변형 또는 파손되어 조향축(53)의 길이를 축소시켜 충격력을 감쇄시킬 수 있도록 된 일종의 실린더이다.The operation mechanism is provided in the first half of the vehicle 51 as shown in Figures 3 and 4 and consists of a steering wheel 52, a steering shaft 53 and a steering column 54, the steering column 54 ) Is a kind of tube surrounding the steering shaft 53, which is a kind of cylinder that is deformed or damaged during a front collision of the vehicle to reduce the length of the steering shaft 53 to reduce the impact force.

상기와 같은 조향컬럼(54)은 차량(51)의 충격시에 조향컬럼(54)이 조향축(53)방향으로 압축되어 변형되어 그 길이가 축소되는 것으로 차량의 정면충돌시에 인체에 탄성을 주는 에어백(55)의 공간을 극대화 할 수 있도록 되어 있다.As described above, the steering column 54 is deformed by compressing the steering column 54 in the direction of the steering shaft 53 when the vehicle 51 is impacted, thereby reducing its length. Note is to maximize the space of the airbag (55).

상기에서 차량의 정면충돌시에 사용되는 에어백(55)은 조향휠(52)에 장착되어 있어 그 충격흡수 공간이 인체와 조향휠(52) 간의 이격거리로 한정되어 지도록 되어 있다.The airbag 55 used at the time of the front collision of the vehicle is mounted on the steering wheel 52 so that the shock absorbing space is limited to the separation distance between the human body and the steering wheel 52.

즉 에어백이 인체의 충격에너지를 흡수하는데 사용되는 공간은 인체와 조향휠 간의 이격거리로 결정되는 것으로 상기 이격거리를 효과적으로 확보할 수 있는 충격흡수방법이 필요로 대두되고 있다.That is, the space used to absorb the impact energy of the human body is determined by the separation distance between the human body and the steering wheel, and a shock absorption method capable of effectively securing the separation distance has emerged.

종래에는 상기와 같은 차량(51)의 정면충돌시에 조향휠(52)과 인체와의 이격 거리를 증대하기 하여 조향컬럼(54)의 붕괴 및 변형을 가해주는 것으로 이루어져 있으며, 이것은 차량의 정면충돌시에 에어백(55)의 작동으로 인체와 조향휠(52) 간에 에어백(55)이 존재하도록 하여 에어백(55)을 통해 가해지는 인체의 충격반발력에 의해 상기 조향컬럼(54)이 붕괴되거나 변형되어 조향축(53)의 길이를 축소하므로써 조향휠(52)과 인체와의 이격거리를 증대하도록 되어 있다.Conventionally, when the front collision of the vehicle 51 as described above to increase the separation distance between the steering wheel 52 and the human body consists of applying the collapse and deformation of the steering column 54, this is the front collision of the vehicle When the airbag 55 is present between the human body and the steering wheel 52 by the operation of the airbag 55, the steering column 54 is collapsed or deformed by the impact repulsive force applied through the airbag 55. The distance between the steering wheel 52 and the human body is increased by reducing the length of the steering shaft 53.

그러나 상기와 같이 인체의 충격반발력에 의해 조향축의 길이를 축소하여 조향휠과 인체와의 이격거리를 증대하는 종래의 방법은 상기 조향컬럼의 붕괴 내지 변형이 충분히 이루어지지 못하는 경우 인체에 더욱 무리한 충격을 주어 인체의 손상정도를 심하게 하는 문제점이 있었다.However, the conventional method of increasing the separation distance between the steering wheel and the human body by reducing the length of the steering shaft by the impact repulsive force of the human body as described above is more unreasonable impact on the human body when the steering column is not collapsed or deformed sufficiently. Given the problem of serious damage to the human body.

본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 차량의 정면충돌시에 ACU의 제어에 의한 에어백의 방출과 동시에 조향컬럼을 인위적으로 붕괴하도록 하여 조향축의 길이를 일정한 길이만큼 축소하게 하므로써, 조향휠과 인체와의 이격거리를 충분히 확보하여 에어백의 충격흡수를 극대화하므로서 인체에 전달되는 충돌충격을 극소화하게 하여 인체가 손상을 받지 않도록 된 차량의 조향장치의 조향컬럼을 제공하는데 있다.The present invention has been made to solve the conventional problems as described above, an object of the present invention is to artificially collapse the steering column at the same time as the discharge of the air bag by the control of the ACU during the frontal collision of the vehicle to the length of the steering shaft The steering wheel and the steering body of the vehicle to minimize the impact shock transmitted to the human body by maximizing the shock absorption of the airbag by securing sufficient separation distance between the steering wheel and the human body, thereby minimizing damage to the human body. To provide a column.

상기한 본 발명의 목적을 달성하기 위한 본 발명의 차량의 조향장치의 조향컬럼은 에어백이 내장된 조향휠과 조향장치의 기어기구에 조향력을 전달하는 조향축을 연결하는 실린더상의 조향컬럼에 있어서, 상기한 조향컬럼의 일측 부위에는 ACU의 제어에 의해 폭발하는 화약이 내장된 붕괴실린더가 연결되어 마련되는 것을 특징으로 하고 있다.In the steering column of the steering apparatus of the vehicle of the present invention for achieving the above object of the present invention in the steering column in the cylinder connecting a steering shaft for transmitting a steering force to the gear mechanism of the steering apparatus and the built-in airbag, the One side of the steering column is characterized in that the explosion cylinder built-in explosive gun is connected by the control of the ACU is provided.

따라서 상기와 같이 에어백(2)의 충격흡수 공간이 충분히 확보되므로서 에어백(2)에 의해 인체에 전달되는 충돌충격이 현저히 흡수되어 감쇄되므로서 인체가 충돌에 의한 손상을 보다 적게 입을 수 잇도록 되어 있다.Therefore, as described above, the shock absorbing space of the airbag 2 is sufficiently secured, and the impact shock transmitted to the human body by the airbag 2 is remarkably absorbed and attenuated so that the human body can be less damaged by the collision. have.

상기한 바와 같이 본 발명의 차량의 조향장치의 조향컬럼는 차량의 정면충돌시에 ACU의 제어에 의한 에어백의 방출과 동시에 붕괴실린더에 의해 조향컬럼을 인위적으로 붕괴하도록 하여 조향휠과 인체 사이의 공간을 충분히 확보하여 에어백의 폭을 확대함으로써 에어백의 충격흡수를 극대화하고, 인체에 전달되는 충격에너지를 낮은 충격도로 더욱 안전하게 하여 승객을 보호할 수 있도록 하는 효과가 있다.As described above, the steering column of the steering device of the vehicle of the present invention artificially collapses the steering column by the collapse cylinder simultaneously with the release of the airbag under the control of the ACU during the frontal collision of the vehicle, thereby creating a space between the steering wheel and the human body. Ensuring that the airbag is sufficiently secured to maximize the shock absorption of the airbag, and the impact energy delivered to the human body can be more safely protected with low impact to protect the passengers.
